These technical changes are described in H2. Also, some technical terms in references [E2] and [E3] have been changed in order to unify the terminology used in all the CCSDS Recommended Standards that define space link protocols, as well as to define these schemes as general communications schemes. These terminology changes are listed in H3. H2 TECHNICAL CHANGES H2.1 PARAMETERS ASSOCIATED WITH TRANSFER FRAME LENGTH In references [E2] and [E3], the periods during which the value of parameters are fixed are not consistently specified. In this Recommended Standard, any parameter associated with the length of the Transfer F...
